The account promises to help users track their individual purchases, while also maintaining a shared transaction area and goal(s) that includes an Our Safe-to-Spend number across both users. Users would be able to simply transfer money to each other as well. And interestingly, it appears that any two people (and maybe more?) will be able to sync their Simple accounts together, it won’t have to be an actual legal joint account. That’s exactly how it should be.

Innovating in the Deposit BusinessThe deposit business is relatively straightforward. There are checking accounts, debit cards, and savings accounts (most paying a negligible amount of interest). So how does a bank differentiate itself in this absurdly low interest-rate environment? Branding, trust and location have been the traditional drivers and are still vital. And every decade or so a new technology comes along and there is some jostling along the way until everyone offers it (ATMs, VRUs, debit cards, online banking, mobile banking, etc.).

But even in a world where every FI offers the same basic product lineup, there are still ways to add value and increase market share and/or margins. Synced joint accounts, like Simple’s Shared Account. Married couples are the biggest opportunity, but there are other segments as well: Parents that need to sync with their kids. adults that need to sync with their aging parents, employers with employees, advisors with their clients, and so on.

There has been progress on this front. Many (most?) business accounts offer ways to enable third-party accountant/advisor access. Person-to-person transfers make it easy to send money to kids at college. And PFM solutions such as Mint, allow money-tracker couples to keep an eye on their spending across multiple accounts.

Bottom line: Existing solutions are often difficult to use, missing key features, and not fully integrated within big-name financial brands. Simple, which already offers a state-of-the-art checking account with Safe to Spend balance forecasting, natural-language search, and overall great UI, is expected to raise the bar considerably when Shared Accounts launches. I look forward to using it.
